Complex tissues are not found in

Options

A. Few bryophytes
B. Pteridophytes
C. All gametophytes
D. All spermatophytes.

Answer

**Step-by-Step Solution:**

1. **Understanding Complex Tissues**: Complex tissues are defined as tissues that are made up of more than one type of cell and work together as a unit. The main examples of complex tissues in plants are xylem and phloem.

2. **Identifying the Options**: The options provided are:
- A) Few bryophytes
- B) Pteridophytes
- C) All gametophytes
- D) All spermatophytes

3. **Analyzing Each Option**:
- **A) Few Bryophytes**: Bryophytes are primitive plants that do not have vascular tissues (xylem and phloem). Therefore, they do not have complex tissues.
- **B) Pteridophytes**: Pteridophytes are vascular plants that have differentiated roots, stems, and leaves. They possess complex tissues (xylem and phloem).
- **C) All Gametophytes**: Gametophytes are haploid structures that do not have vascular tissues. They are generally simple in structure and do not possess complex tissues.
- **D) All Spermatophytes**: Spermatophytes (seed plants) include gymnosperms and angiosperms, both of which have well-developed vascular tissues.

4. **Conclusion**: Based on the analysis, both bryophytes and gametophytes do not have complex tissues. However, since the question asks for the group that does not contain complex tissues, the correct answer is **C) All gametophytes**.

5. **Final Answer**: Complex tissues are not found in **all gametophytes**.
